My application runs normally all the time without getting any BadImageFormatException. But if no user interaction happens for more than half an hour and user clicks on one particular menu then application crashes with System.BadImageFormatException. This is happening for one particular toolstrip menu item only but not in normal circumstances.
Please let me know the solution as soon as possible.

i got a problem with bitonal image. when i do resizing it's losing it's quality and image losing it's viewability. i am facing this issue with .net gdi+. i also tried converting bitonal image to 32bits bitmap and then resizing it using smoothing with both bilinear and bicubic interpolation. but no use. is there any other way?

This is probably a really basic question but I can't figure it out for the life of me. I am running VS.Net ver 7.0.9466 with .Net Framework 1.0.375. On every other version I have seen, there are lines in the text editor that divide sub routines to make it easier to distinguish where on sub ends and the other begins. This version does not show these lines. Is there a setting or option that needs to be enabled or is this feature just not available on this version?

My recollection says that it did show these lines, but this article disagrees[^]. I don't recall if there was an option to turn them on. In Visual Studio .NET 2003 the option is in Tools, Options under Text Editor, Basic, VB Specific and is named Show Procedure Line Separators.
C# and C++ do not have this feature in any version of Visual Studio.
I don't know of many people still using VS.NET 2002 and .NET Framework 1.0. Virtually everyone upgraded to VS.NET 2003 and .NET 1.1 (it helped that for several months, the upgrade only cost £19!)
Personally I ensure there are multiple blank lines between procedures in any case. For me, that's enough of a separator.

Hi
I wrote a multi thread program (windows service) that writes to a log (text) file.
So I used beginInvoke so that only one thread will write to the file.
When I tested it on my machine it worked fine but when I installed the program on a multi processor production server it crashed.
Code:
Public Delegate Sub DelegateLogError(ByVal txtMsg As String)
Public Class Server_main
Private log_ As LogHandler
Public Sub logError(ByVal txtMsg As String)
Dim del As New DelegateLogError(AddressOf log_.LogError)
Dim ac As AsyncCallback = New AsyncCallback(AddressOf cbLogError)
del.BeginInvoke(txtMsg, ac, Nothing)
End Sub
Public Shared Sub cbLogError(ByVal ar As IAsyncResult)
If ar.IsCompleted Then
Dim del As DelegateLogError = CType(CType(ar, _
System.Runtime.Remoting.Messaging.AsyncResult).AsyncDelegate, _
DelegateLogError)
del.EndInvoke(ar)
End If
End Sub
Protected Sub Initialize()
Try
logError("Starting Server")
.
.
.
End Class
Does anyone have any idea how to make it work on a multi processor?
Thank you
Adam

Hi,
This looks like Basic.NET doesnt it ?
If it runs fine on a single-processor and fails on a multi-processor, then I would
suspect you have some thread synchronization problem; but I would expect it to be
elsewhere, not in code that you force to run on the UI thread.
Why is it you think the logging is causing the problem ??
To investigate, you might replace your logging stuff by simple Console.WriteLine()
operations (or whatever is equivalent in Basic.NET); remark that Console by itself
is multithread-safe.

Hi,
your usage of BeginInvoke doesn't say that your log method is only called by on thread at a time. You have to lock it instead:
'class variable
Private objMyLock As Object = New Object()
Public Sub LogSafe()
SyncLock objMyLock
'Do your logging here
'Once one thread has passed SyncLock all next threads
'will stop there until this thread has exited the block.
End SyncLock
End Sub

Hi
yes you are right it didn't work on one thread
so I used monitor.enter and monitor.exit instead.
Thank you

Hi all,
i am new to .net. could anyone help me to learn about the programming fundamentals of vc++ .net in visual studio 2005.If it is possible send some tutorial link and sample simple programs in vc++ .net..
thanks in advance..

You should find several tutorials here in codeproject. Do you specifically want to do .NET development in C++ or any kind of development, e.g., MFC, ATL, in VC++?
You can look here:

hi,
At this time i'm ready to do the OCR project based on CLR in vc++. But, my code snippet giving an error when the c++/clr compile the particular line....
void Form1::SOCR_Click(System::Object^ sender, System::EventArgs^ e)<br />
{<br />
int i,j,k;<br />
String^ fName = "Citi.tif";<br />
MODI::Document^ doc = gcnew MODI::DocumentClass(); <br />
doc->Create(fName);<br />
doc->OCR(MODI::MiLANGUAGES::miLANG_SYSDEFAULT,true,true);<br />
<br />
for(i=0; i < doc->Images->Count; i++)<br />
{<br />
MODI::Image^ img =(MODI::Image) doc->Images[i];<br />
}<br />
<br />
}
where,
Image - Interface class
The Error is...
Error 1 error C3149: 'MODI::Image' : cannot use this type here without a top-level '^'
please help me...
thanks in advance...

I'm not familiar with C++/CLI but as Christian says below you may be better off attempting this in C#. However, you might have more luck posting this question in the C++/CLI forum.

C# is a better language to use to learn .NET

Forgive me if I sound ignorant
But the main difference between Visual Studio and Visual Studio .NET
Is the formaer user SDK for Windows Interface while the Latter .NET
|
|
|
|
|
Yes, basically.

One more question If I want to learn .net pogramming would the academic version of Visual Studio be good enough or Should I purchase the Porfessional Edition
|
|
|
|
|
It all depends on your needs. If you are just learning how to use a language and/or .Net, then I would suggest the Express version. Here is a comparison chart if you need it:

I have Visual Studio Team Edition for SoftWare Developers but that isn't the same as Visual Studio .NET
Why would it have a different name
|
|
|
|
|
Everything is Visual Studio. There are just different editions, e.g., VS Standard, VS Pro, VS Team Edition for developers, which is what you have. VS .NET was just the name for the 2002 and 2003 versions.

So If I have Visual Studio Team Edition for SOftware Developers I can projects that use the .NET interface as opposed to MFC ???
Probably could mix it up to whitin one solution
Thankx ???

You can have several .NET projects in one solution. And you can add MFC projects as well, if you like.
